This study focuses on the fabrication and electrical characterization of a polymer composite based on nano-sized varistor powder. The polymer composite was fabricated by the melt-blending method. The developed nano-composite was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FeSEM), and energy-dispersive X-ray spect...

Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4-C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4-C2H6O2 (Nickel zinc ferrite-ethylene glycol), Fe2O4-C2H6O2 (magnetite ferrite-ethylene glycol), NiZnFe2O4-H2O (Nickel zinc ferrite-water), MnZnFe2O4-H2O (manganese zinc ferrite-water), and Fe2O4-H2O (magnetite fe...

introduction: a desirable quality of any endodontic sealer is its ability to be tooth color friendly. therefore the aim of the present study was to evaluate the tooth discoloration potential of a nano zinc oxide-eugenol (nzoe) sealer. methods and materials: in order to evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral incisors were filled with one of the s...

This research focuses on the integration between functional finishing and performance properties of polyester fabric for comfortable clothes. The effects nanofinishing (zinc oxide nanoparticles nano-polyurethane nanocomposite) ultraviolet protection fabric, whiteness index, Kawabata Evaluation System were studied. Under optimum conditions, excellent (150) was achieved at lower concentrations na...

The study was conducted in the wooden canopy of Department Horticulture and Landscape Engineering / College Agriculture Tikrit University during growing season 2021-2022, to effect spraying with glutamic acid nano-zinc oxide on some vegetative growth characteristics, mineral content, active substance anatomical characteristics Lavendula Angustifolia Mill. A factorial trial carried out two facto...

This study examines zinc(II)–chitosan complexes as a bio-sorbent for phosphate removal from aqueous solutions. The bio-sorbent is prepared and is characterized via Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Point of Zero Charge (pHPZC)–drift method. The adsorption capacity of zinc(II)–chitosan bio-sorbent is compared with those of chitosan and ZnO–c...

Organic-sulfur-zinc hybrid materials were prepared via polycondensation of Zn(OAc)2 and trithiols bearing various alkyl groups. A soluble nanoparticle could be obtained by the polycondensation using a trithiol bearing octadecyl moieties. The good dispersing ability as nano-scaled particles was confirmed by dynamic light scattering and atomic force microscopy analyses. This hybrid nanoparticle w...

In this study, the effect of adding zinc oxide nanoparticles (ZnO) on general color change and transparent adhesion strength polyester folds was studied in wood (Ulmusglabra). Zinc with concentrations 0, 0.22, 0.20,1, 1.20 2% coating weight were combined. a study about adherence resistance results showed that highest Nano coatings contained 1% oxide, more than had negative coating. case change,...

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...
